5 Adjust the knob for the desired output current.
Check that the
Limit annunciator still flashes. Set the knob for current control.
The second digit of the ammeter will be flashing. Change the flashing digit using
the resolution selection keys and adjust the knob to the desired output current.
6 Return to the meter mode.
Press key or let the display time-out after several seconds to return the
meter mode. Notice that the
Limit annunciator turns off and the display shows
“OUTPUT OFF” message.
7 Enable the output.
The
OFF annunciator turns off and the 8V* (or 25V**) or 20V* (or 50V**), OVP,
OCP and CC annunciators are lit. Notice that the display is in the meter mode.
In the meter mode, the display shows the actual output voltage and current.
8 Verify that the power supply is in the constant current mode.
If you operate the power supply in the constant current (CC) mode, verify that
the
CC annunciator is lit. If the CV annunciator is lit, choose a higher voltage
limit.
Note During actual CC operation, if a load change causes the voltage limit to be exceeded,
the power supply will automatically crossover to constant voltage mode at the preset
voltage limit and the output current will drop proportionately.

You can use the resolution selection keys to move the flashing digit to the
right or left when setting the voltage.
